SPECIFICATION forming part of Letters Patent No. 513,100, dated January23, 1894.

Application filed February 1, 1893. $erial No. 460,598. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD L. FORD, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,haveinvented or discovered certain new and usefullmprovementsin Furnaces, ofwhich improvements the following is a specification.

The invention described herein relates to furnaces adapted for thestorage of ingots, billets, puddle balls, .&c., where they may be keptin a heated condition, or the temperature of the metal slightly raised,until they can be transferred and worked by rolls and hammer, &c.

It frequently happens that the ball, ingot or billet, when the latter isformed in a rotary puddler, is larger than can be conveniently oreffectively worked in the rolls or under the hammer, and it is thereforenecessary to divide the ingot, ball or bloom into two or more partswhich are to be separately worked.

It is a further object of this invention to provide suitable means inconnection with a furnace whereby the ingot, ball or bloom can bedivided, and the portions not required for immediate'use may be retainedin a heated condition.

In general terms, the invention consists in the construction andcombination substantially as hereinafter more fully described andparticularly claimed.

In the accompanying drawings which form a part of this specification,Figure 1 is a sectional elevation of my improved furnaceand shearingattachment, the plane of section being through the longitudinal axis ofthe furnace, and Fig. 2 is an end elevation of the furnace.

In the practice of my invention, the furnace 1 is made of sufficientlength to permit of the insertion therein, and on thehearth 2 of thefurnace, of the longest bloom, ball or ingot which it is probable willbe made in the plant to which the furnace belongs. At one end of thefurnace is formed a fire chamber 3, in whichmay be burned either solidfuel, gas, or a liquid fuel.

The hearth 2 of the furnace is formed by a frame 4, consisting ofsuitable structural beams, and mounted on suitable trucks 5; The wheelsof these trucks are arranged on rails 6, which extend beyond the end ofthe furnace a distance at least equal to the length of the hearth, sothat the latter may pass entirely out of the furnace for convenience inplacing an ingot, ball or bloom thereon. The bed of the hearth is formedby brick or other refractory material supported by the frame 4. The rearend of the furnace is made open so as to permit the passage of themovable hearth just described, and any load which may be placed thereon,into and out of the furnace. The furnace is closed above the hearth by asliding door 7, which is preferably supported in its lower position bythe hearth.

At the end of the furnace, and preferably in such close proximitythereto as to form portions of the guide for the door, is erected aframe 8, the vertical posts thereof being arranged a distance apart,preferably a little greater than the width of the hearth, so that thelatter may pass freely between them. These vertical posts serve asguides for the shear-blade 9, which is attached near its ends to rods10, connected at their lower ends to the cross-head 11, which,-in turn,is connected to the piston rod 12,0f a fluid pressure cylinder 13. I

In the use of my apparatus, the furnace having been properly heated, theingot, ball or bloom is placed upon the hearth 2, which is run out forthat purpose, and after the ingot or ball has been placed thereon, ispushed back in to the furnace, and the door 7 thereof closed. The ingot,ball or bloom will thus be kept hot until such time as it can be workedby the hammer or rolls. If the ingot, ball or bloom is larger than isdesirable to be Worked at one time by the hammer, the hearth 2 is runout of the furnace until so much of the ingot or ball as is to beworked,is beyond the line of movement of the shear-blade 9, whereuponthe latter is moved down, dividing the ingot or ball at the desiredplace. The part thus severed is then transferred to the hammer, and thehearth again returned to the furnace, and the door 7 lowered, so as tokeep the remaining portion of the ingot, ball or bloom hot until suchtime as it or any portion thereof is to be transferred to the hammer.This arrangement of a shearing mechanism adjacent to a heating orsoaking furnace, permits of the ready separation or dicombinationtherewith a hearth movable into and outof the furnace, and. a shearingmechanism arranged to shear or divide an ingot, ball or bloom restingupon the hearth, substantially as set forth.

In testimony whereof I have hereunto set my hand.

EDWARD L. FORD.
